I was using mysql 5.6.11,it usually turned down and show me this:
2005 - Unknown MySQL server host 'localhost'(11001).
Currently my resolution is to turn off the network,than it return to normal.I had searched a lot,but no answer is revalent to it.So,does anyone knows the reason?
This question is related to
mysql
ERROR 2005 (HY000): Unknown MySQL server host 'localhost' (0)
modify list of host names for your system:
C:\Windows\System32\drivers\etc\hosts
Make sure that you have the following entry:
127.0.0.1 localhost
In my case that entry was 0.0.0.0 localhost which caussed all problem
(you may need to change modify permission to modify this file)
This performs DNS resolution of host “localhost” to the IP address 127.0.0.1.
The case is like :
mysql connects will localhost when network is not up.
mysql cannot connect when network is up.
You can try the following steps to diagnose and resolve the issue (my guess is that some other service is blocking port on which mysql is hosted):
This should ideally resolve the issue you are facing.
I have passed through that error today and did everything described above but didn't work for me. So I decided to view the core problem and logged onto the MySQL root folder in Windows 7 and did this solution:
Go to folder:
C:\AppServ\MySQL
Right click and Run as Administrator these files:
mysql_servicefix.bat
mysql_serviceinstall.bat
mysql_servicestart.bat
Then close the entire explorer window and reopen it or clear cache then login to phpMyAdmin again.
